We just got our cube a couple of weeks ago. We could not possibly be more pleased. For the price, this is the best car on the market. If you can live with the styling, you get so much comfort, ease of access, mpg, and functionality in a well-designed package.
The CVT is seamless, the engine is powerful enough for the size, the road noise is comparable to many near-luxury cars (there is some significant wind noise). The driving position is perfect for both me (6' 7''/220) and my wife (5' 1'').
The only thing this car needs is a center console.
